The Bandmaster
''Men ought to know that from the brain and from the brain only arise our pleasures, joys, laughter, and jests as well as our sorrows, pains, griefs and tears...It is the same thing which makes us mad or delirious, inspires us with dread and fear, whether by night or by day, brings us sleeplessness, inopportune mistakes, aimless anxieties, absent-mindedness and acts that are contrary to habit...''
Hippocrates The Sacred Disease (IV century before. J.-C.)
Anatomy
Note: cette page n'est qu'une présentation des régions du cerveau et de leurs fonctions dans le but d'être un repère pour lorsqu'on nous abordons certains déficits/ problèmes reliés à certaines régions
The brain is divided into four sections called lobes. Each lobe is related to specific fonctions. However, it is crucial to understand that lobes interact with each other, they send messags to one another. If one of them is injured, problems related their fonctions or fonctions regulated by other lobes regarding interrupted connections can occur.
Frontal Lobe
This part of our brain is located right above our eyes. This section is involved in :
1- Language production
2- Odor detection
3- Resolving problems, concentration and planning (executive fonction)
4- Traction
Occipital Lobe
It is located in the neck and plays a major role for our vision.
Parietal Lobe
This region is located in the middle of the brain and is related to :
1- The sense of touch and pressure
2- Taste
3- Body sensation
Temporal Lobe
Intersecting the other regions, this lobe is involved in:
1- Hearing
2- Face recognition
Orientation
Sometimes, it is possible to talk about a specific region. Therefore, we use specific names. For example, to describe the external part of the parietal lobe, parietal median lobe can be used instead. Here are some names that are used to describe different possible orientation:
Dorsal = the top Median = the center
Ventral = the bottom Dorsolateral = the top and outside
Lateral = outside Ventromedial = the bottom in the middle
Decussation
Decussation refers to a hemisphere of the brain that orders and receivs informations of the opposite half part of the human body: the right side of the brain controls the left side of the body and the left side of the brain controls the right side of the body.
Structures
Key structures that regulates different sides of the body and their functions:
